neg chassis cable badly melted, now no power 2 ecu

[s'ko]

92 svx

wife was driving & car died ion her

now there is no cel when keyed on

 

Here is the diagnosis

 

Timing belt is fine.

Fusible link 2 is not blown.

No interior or exterior fuses are blown.

Negative lead to the chassis is a melted badly.Â*** Plastic battery tray is melted by the wire and the battery is leaking.Â*** I removed the negative wire and trimmed it until I found clean wire and then put it to a bolt on the frame rail near the tranny fluid filter.Â*** I also replaced the battery.

I still don’t think I am getting power to the ECU b/c the check engine light does not turn on when keyed to on and the fuel system does not power up.Â*** Where does the engine ground come from?Â*** Could there be a bad ground there that is not closing the circuit.Â*** Did I fry my ECU?Â*** Where is the ECU located?

 

Anyone else have this happen and how did you fix it.

 

Thanks

There should be some fusible links somewhere and they should be checked out. Make sure they are good and making good connection. Use a test light probe to check for power and where it is getting to. There could be a problem with the ignition relay so check that also. The ignition switch is another possible trouble spot.

all fusible links are good

no blown fuses

car turns over but there does seem to be any spark

 

someone on another board suggested checking grounds

 

will do that this evening

Then check to see if power is getting to and past the ignition switch. Hopefully you are using a test light probe to verify where power is getting to. You can't just assume power is getting to the fuses and other areas.
